TPC-C, short for Transaction Processing Performance Council Benchmark C, is a benchmark used to measure how well a database holds up when it’s trying to run certain workloads. TPC-C is specifically an OLTP benchmark, and it’s widely recognized and standardized. TPC-C simulates an environment where a lot of users are making requests of a database, and then it measures how well the database holds up – i.e., how fast it can complete the transactions, what the cost of completing the transactions is, and so on.
